AttributeError with cr.pl.gene.trends about cellrank HOT 5 CLOSED

Hi @MarieCoutelier, it might just be a problem with GATA1, try excluding that gene and see whether it runs. If not, try using cr.models.GAM (rather than GAMR), which is based on pygam. This is easier to install and run because it does not require rpy2.

@michalk8 is the expert here but is currently not available, let's see what he says when he gets back.

I think the problem is because mgcv is not installed in that environment; here is code used for loading it using rpy2 and here it's being called. Would check whether model._lib is None or not (will change to raise an error by default in the future if mgcv is not present).

I suppose @michalk8's comment from above solved the issue; closing.

Hi, I get the same error when following the tutorial in the "Visualize expression trends" section.
I tried excluding GATA1, and using GAM instead of GAMR, but no success.
I have rpy2 installed in my environment and mgcv installed in R.
Any other suggestions?
Thanks

for me using GAM instead of GAMR worked in this case.
also mgcv was missing but no error message etc. would have indicated it, installing mcvg resolved the issue.
